What if the coin goes DOWN?
Can you profit buying the coin (shorting BTC is very difficult from what I understand) if the exchange rate drops? A miner can.
Purchase miner for 0.75BTC. Mine 0.375BTC. BTC goes down to say $100. You have 0.375BTC worth $37.50.
Don't purchase miner, keep the .75BTC. BTC goes down to say $100. You have 0.75BTC worth $75.00.
No matter what happens with the exchange rate of BTC or whether it goes up or down, 0.75BTC is always more than 0.375.
At this point I simply refuse to believe that anyone can be this obtuse or ignorant. You must be trolling.
I thin it's YOU who is trolling...
BTC @ $600(USD) I Buy 1 coin
BTC @ $600(USD) I buy mining equipment for 1 coin
BTC @ $550(USD) My one coin is worth $550
BTC @ $550(USD) My mined amount can go OVER $550
because I can mine 1+BTC with it.Are you so obtuse or ignorant that you cannot understand something this simple?
So you're finding the magical miner that makes more BTC than it's initial outlay. Not one BFL device did that. Not one Cointerra. Not one Hashfast. Not one Black Arrow. None of the Avalon B3s.
THe first 2 Avalons, the first KNC Jups, and the first S1s did this.
Dragon, Rockminer, SP30s won't.
Good luck.
you are assuming quite a bit saying a dragon will not do roi in btc. it could. you have no idea of power cost for someone. put in 1th with 0 power cost it will get a lot of coins.
also there is a power wall for asics. and it will be reached when it is reached growth will slow to a crawl.
if power wall is .2 watts diff will max near 600g since no one could earn money even with 8 cents a watt.
and if the power wall is .35 watts diff maxes near 400g at 8 cents
so at a diff of 600g and free power the dragon keeps earning money.
So free power people with smaller rigs will never disappear.
I made roi with s-1's purchased in may
3 for 1.15 btc how did i do it. power at an 84 % discount. 14 cents a kwatt cost me under 2.5 cents. So I will never be fully pushed out of mining due to my power discount.
Well you're obviously the exception to the rule. Maybe the OP was overstating it by saying it's "impossible". But the sentiment is still true for 99% of us.
